GEAR-SI-IIF'IING LEVER- ea ers.

Application filed April 21,

levers. which may be constructed comparatively cheap, and of parts whichare preterably stamped or forged, resulting in a very light and compactassembly.

These, and various other objects. will clearly appear from the.following descrip tion, taken in connection with the accompanyinpdrawings which form a part of this specification. and in which:

Figure 1 is a side elevation. with portions broken away. or a motorvehicle gear box,

embodying a preterred form of my invention.

Fig. 2 is a transverse vertical section substantially along the line'2-2 of Fig. 1,. showing the shifting lever tilted; and

Fig. 3 is a plan view ot' my invention with a part 01 the lover brokenaway.

Reterrin g to the drawings. 10 is a motor vehicle gear box adapted tohouse a change speed gearing. comprising a countershatt 11 and a drivingshaft li having a pair of gears 13 and 14 splined thereon againstrelative rotational movements, but adapted for a sliding movementthereon. Each of the slidable gears 13 and M- respectively, is providedwith a grooved collar 15 in which may be mounted a shifting fork 16,formed with a slotted portion 17, which is adapted to be engaged by thelower ball end 18 of a shifting lever 19.

A cover 20 havingan upwardly extending pedestal 21 may be suitablysecured to the gear box 10, as by bolts 22. The pedestal 21 is formedexteriorly and interiorly thereof adjacent. its upper end withhemispherical dome surfaces and 24 respectively. The shittinglever 19 isadapted to be inserted ,in the hollow pedestal 21 through the upper domeopening 25.

A hemispherical shaped cap member 26, preferably formed oi a stamping isadapted to he slipped over the handle portion 27 of Specification ofLetters Patent.

est

o' r i' the ocdssta This member is adapted to be secured to the shittinglever l!) and oi: spherical or ball surface 2?) I the lever by suitablemeans such as. a pin 28, these parts forming a ball and socketconnection.

The lever 1%.) is yieldingly seated against an upward movement byarrangiim' another hemispherical shaped head member 12%) against theinteriorly 'lornied domev surlace A. This head member being held in.position by suitable means such as a spring: it). the lower end ot whichmay abut against a shoulder 31 shown as tormed integral .vith the lowerend of the lever.

Means for preventing the rotation oi the lever relative to the. pedestalmay be provided in the form of a plurality of pins 23 suitably rivetedin the pedestal with the slotted portions Bl, which are formed in thecap member 26 surrounding the same. ll'ith this construction it will benoted that, the head and cap members may be oscillated, relative to thepedestal dome while. being prevented from relative rotation thereon.

It will be noted that l have provided a mounting which comprises verysimply constructed members, yieldingly mounted on the hollow pedestalmember, and that the gear shifter lever is practically lioated therein.

While l have described and will specifi- "ally claim what i deem to be apreferred embodiment of my invention, it. will be obvious to thoseskilled in the art, that various inoditicatimis and changes may be madewithout departing from the spirit and scope hereof.

Having thus described my invention, what I claim and desire to secure byLetters Patent is:

1'. In a device of theclass described, the combination of a hollowpedestal. having a dome with a central opening, a tiltable leverprojecting through the opening therein, and

ended pedestal, formed interiolly and exteriorly thereof, withhemispherical surfaces, cimiplement-ary members adapted to rest againstsaid surfaces, means for securing one of said members to said lever, and yielding means between the other member and said lever formaintaining both 01 said members in contact with said surfaces to floatsaid lever thereon.

The combination oi a. hollow open ended pedestal having a. hemisphericalsurface r'ormed exteriorly thereof, a lever adapted to he passed throughsaid o iiening, a cap manila-r eormected to said love and. resting onsaid spherical surface, and means for yieldingrly manila-iningg said capmemher on said pedestal to support said lever thereon,

The con'ihination of a holloivopen ended pedestal having formedexteriorl and interiorly thereof oppositely disposed lKlHlSpllQliCRlsurfaces, a lever adapted to be passed through said opening, membersadapted to be arranged against each of said surfaces. and meanscomprising a spring device for supporting said lever in said pedestal ina till-able relation.

3. A gear shiit rzicchanisn'i coniprisil a hollow' open ended pwleslalFormed with interim-l3 and exteriorly disposed hemispherical surfaces,members adapted to rest against each of said surfaces, one of saidmembers being fixed to said lever, and yielding means between the othermember and said lever, said memhers iln'ininp; the sole support of saidlever.

T. A. gear shifting device comprising a fill box. a hollow open endedpedestal ar- "anged thereoi'i, and formed exteriorly and nteriorlythereof with oppositely disposed iemisphorical surfaces, a tiltahielever adapted to be passed through said opening,

a cap member secured to said lever and adapted to be supported on saidoutside spherical surface, a head member adapted to be arranged againstsaid inside spherical surface, a collar arranged on said lever and aspring between said collar and said latter mentioned cap member, wherebysaid lever is supported in said pedestal.

8. A gear shifting device comprising a gear box, a hollow open endedpedestal.

mounted thereon, and formed with an out side and an inside hemisphericalsurface, a pair of stampings arranged against each of said surfaces, alever adapted. to be passed through said opening, one of said stampingsbeing secured to said lever, and spring means between. the otherstamping and said lever n'herehy said-lever is supported in saidpedestal.

9. The comloination of a hollow open ended pedestal having a sphericalsurface formed thereon, a tiltable lever adapted to be passed throughsaid opening, a cap member secured to said lever and adapted to rest onsaid surface, and means for preventing relative rotational movementbetween said cap and said pedestal, While permitting relative tiltingmotions therebetweon.

10. The combination of a hollow open ended pedestalhavinga'hemispherical surface formed exteriorly thereof, a tiltablelever adapted to be passed through said ()[)Oi'1l1i,{, a cap membersecured to said lever and adapted to rest on' said surface, said capmember hai ing a slot formed therein;

a pin arnnged in said slot and secured to said pedestal for preventingrelative rotational movements between said cap member and said pedestalWhile permitting relative tilting movements therebetween.

In testimony whereof I ailix my signature.
